What are the advantages and disadvantages of splitting data into separate arrays versus combining them into one array in PHP?

When deciding whether to split data into separate arrays or combine them into one array in PHP, it's important to consider factors such as data organization, ease of access, and performance. Advantages of splitting data into separate arrays include better organization and easier manipulation of specific subsets of data. On the other hand, combining data into one array can simplify data access and reduce the number of variables to manage. Here is an example of combining data into one array in PHP: 

// Splitting data into separate arrays
$user1 = [
    'name' => 'John Doe',
    'age' => 30,
    'email' => 'john.doe@example.com'
];

$user2 = [
    'name' => 'Jane Smith',
    'age' => 25,
    'email' => 'jane.smith@example.com'
];

// Combining data into one array
$users = [
    $user1,
    $user2
];

// Accessing data from the combined array
echo $users[0]['name']; // Output: John Doe
echo $users[1]['email']; // Output: jane.smith@example.com
